libservo: Allow embedders to signal when the cursor has left the WebView (#37317)

Browse source 
Currently, the hover state will stay when the mouse moves out of the
webview, this PR fixes it

Testing: Hover on the `About` on servo.org, and then move the mouse up
to the browser UI, see the hover state resets
